Case History: OringOne's custom Large O-Ring solution
The Client’s challenge
The client, an Italian company and global leader in cable solutions supporting the energy transition and digital transformation, approached OringOne to identify and solve a sealing issue involving a Large O-Ring.
In this case, the O-Ring was custom-made, specifically designed according to the required dimensions — 24 meters in length and 42 mm in cross section — for the application, where the seal was compromised by fluids and mechanical stresses.
Custom O-Rings are critical sealing components, widely used across industries due to their simplicity and effectiveness in both static and dynamic applications. However, they require careful selection of material, cross section, size, and compound to ensure reliable and long-lasting performance.
Compound research and development
The initial technical challenge concerned non-standard Large O-Rings, for which no catalog compound was available that met the client’s specifications. Our R&D team and laboratory technicians therefore conducted an in-depth investigation to develop a custom compound specifically for this O-Ring.
This special compound was developed with the following objectives:
- Improve resistance to wear and aggressive fluids;
- Optimize sealing performance during compression and release cycles;
- Reduce compression set effects (%), achieving a lower compression set compared to competitors.
Packaging, Production, and Strategic Stock
Once the ideal compound was defined, we selected dedicated packaging and containers capable of preserving the product in optimal conditions, maintaining the elastomeric properties over time and reducing the risk of premature degradation.
In response to the client’s request for shorter delivery times, OringOne accelerated the production process, demonstrating significant flexibility and commitment to urgent requirements. To ensure continuous supply and prevent potential operational slowdowns, a strategic stock of Large O-Rings was established, tailored to the client’s future needs and expected replacement schedules.
Performance testing and results
We conducted a comprehensive series of compression tests, achieving shorter test times and superior performance compared to competitors, confirming the quality of our compound and custom Large O-Rings developed specifically for the application. During testing, key parameters were monitored, including:
- Hardness variation (Shore A);
- Weight variation (%);
- Volume variation (%);
- Compression Set (%), confirming a reduced compression set compared to other solutions.
Thanks to this technical, customized, and results-oriented approach, client achieved:
- A seal with more than double the lifespan of the previous solution;
- Superior performance in compression tests compared to competitors;
- A tailor-made, non-catalog solution, with a custom O-Ring measuring 24 meters in circumference and 42 mm in cross-section;
- Competitive costs, without excessive expenditure;
- A trusted and collaborative relationship, which evolved into a strong partnership between the teams.
The partnership with this Italian company, a global leader in cable solutions supporting the energy transition and digital transformation, demonstrates how OringOne combines technical expertise, product innovation, and customer focus to solve complex challenges in industrial sealing and custom Large O-Rings, even in highly demanding applications.
